Playstyle mode My idea 3 players and 4 player or 2v2 or Tag team

Introduction
In the past, I played EDH with a group of 4 friends. And often the time did not match up, leaving only 3 people. So I thought of playing 3 people at the same time. Let's call it One Way (I have a simple illustration).

1. One Way When Player A attacks in a direction, the attack direction is forced to Player B only. And Player B forces to attack in C only.
2. With instant or sorcery, the target can go in any direction to attack B or defend by targeting C.
3. When 1 player loses, it is cut to 1v1.

• You can leave additional comments so that I can use it to play my EDH group when I go to play at the store. LOL

1. I searched on youtube. I found an MTG game that was released 10 years ago with a 2v2 or tag team system. I think it should be applied in MTG arena.
